When discharging the two times are no use in estimating how long there
is left. This is because there is no indication as to which battery is
the bigger and by how much. In this example the actual time could
reasonably be anything between two and four hours before even trying to
think about usage patterns. (The only reason I know it's not six hours
is that I know it won't last that long from experience.)
For charging example above I have no indication how long the second
battery will take on top of the hour for the first battery; from the
other infomation below I guess it's about another two hours and that's
only easy because the two batteries are at the same percentage.
NB: Battery 2 is not 'charged' it's status will become 'charging' once
battery 1 has got to 100%. And yes the computer does charge the
battries one at a time as this implies.
